Add JetBlue, Ryanair, Cathay Pacific, IndiGo...there are a lot more than 2 profitable airlines worldwide.
But it is hard to compete with a rival that has explicit support from a state. Whether that be owned by the state, or with negotiating advantages from an arrangement like Chapter 11.
Funny when Cathay Pacific is listed among those, all the other three are low cost airlines, while Cathay are consider the "normal" or premium in today's world.
One reason Cathay got to be profitable is because they are one of the 5 largest cargo flight Airline in the world.
